Dr. Granger is hoping to encourage Coker students who are taking math courses to visit the Center for Quantitative Literacy for math tutoring. She decides to conduct a study to find out what types of advertising or incentives might be effective.

a. What is the population for this study?

• a.

All students in MAT 203

• b.

A random selection of 100 Coker students

• c.

All Coker students who are taking math courses

• d.

A random selection of Coker students who are taking math courses

b. Which of the following would be an appropriate research question for the study?

• a.

What percentage of Coker math students say they would visit the QL Center after seeing a flyer in the cafeteria?

• b.

What types of advertising (social media, flyers, etc...) are you most likely to notice for campus services?

• c.

What types of incentives would motivate you to visit the QL Center?

• d.

Would you visit the QL Center if your instructor offered 1 point of extra credit per visit?

c. Which of the following data collection strategies would be best for the study?

• a.

Convenience sample: Only speak with the students who visit the library when the QL Center is open.

• b.

Random sample: Choose 100 random Coker students and email them a survey.

• c.

Stratified sample: Divide Coker math students into groups based on which course they are taking, and then randomly select one section of each course to visit and distribute a survey.

• d.

Systematic sample: Sort all Coker students by student number, and then email a survey to every 10th student.

d. Suppose Dr. Granger uses an appropriate sampling technique, and then distributes a survey that includes the following question:

What motivated you to visit the QL Center?"

A. My instructor offered extra credit

B. I needed help with my math class

C. My friend was going

Would this be a biased, or unbiased survey question?

• a.

Biased, because it assumes the person answering has visited the QL Center, even though they may not have visited.

• b.

• c.

Not biased, because the options include all possible motivations for visiting the QL Center.

• d.

Not biased, because the wording does not lead the answerer to a specific choice.

Question 1)

Population for the study is " all Coker students who are taking math courses"

Option C is the correct answer

Question 2)

Appropriate Research Question would be something which will give Dr. Granger a clue of what would be the thing that would motivate students to visit QL center

Only Option C is the apt question for that. Option D assumes that student would go to QL center

Option C is the correct answer

Question 3)

The population is all Coker students who are taking math courses. So, we need to have a sample that represents that. Selecting from all Coker students by any method is not a good data collection strategy for this case.

We need to have a sample of coker students who are taking math courses, Only Option C satisfy this condition

Option C is the correct answer

Question 4)

The question is biased

Option A is the correct answer
